A laboratory experiment was conducted to study the influence of seed treatment with nanoparticles on seed quality and storability of groundnut at the Seed Technology Research Unit, AICRP on Seed (Crops), University of Agricultural Sciences, Bangalore. Slightly aged seeds of groundnut cv. Kadiri Lepakshi (K-1812) obtained from the Dryland Agricultural Project, UAS, Bangalore were treated with SiO2, TiO2and FeO in both nano and bulk forms, kernels packed in cloth bag, under ambient conditions. Results revealed significant effect of nanoparticles on seed quality and storability in groundnut. Among the treatment combinations, dry dressing treatment with SiO2 NPs@250 ppm recorded higher germination (99, 89,72%), field emergence (90, 80 and 63%) and lower seed moisture content (5.21, 5.75 and 7.42 %) and seed infection (1.33, 8.00 and 25.33 %)at 0, 3 and 6 months of storage followed by SiO2 NPs@500 ppm. Polymer coating treatment also showed better results, but less
compared to dry treatment. Polymer coating treatment with SiO2 NPs@500ppm recorded higher germination (96, 85, 64 %), field emergence (86, 74 and 57 %) and lower seed moisture content (5.45, 5.98 and 7.81 %) and seed infection (1.33, 9.33 and 26.67 %) at 0, 3 and 6 months of storage. As a consequence, the findings revealed the positive influence of nanoparticles and therefore, could be used as safe seed treatment method to enhance seed quality and storability of groundnut kernels.
